Chain processing technology

Abstract

The invention discloses a chain processing technology. The technology includes the following steps that a, heat treatment is performed; b, carburization is performed as follows: parts are placed in heat treatment equipment to be heated and subjected to heat preservation, then a carbon-containing medium is introduced, carbon permeates the surfaces of the parts, and thus the hardness and wear resistance of chains are improved; c, quenching is performed; d, tempering is performed; e, blackening is performed as follows: according to the high-polymer organic polymerization principle, film forming and blackening are performed by the aid of tempering waste heat in the process of the heat treatment technology; f, bluing is performed as follows: the parts are cooled and saponified by the aid of a chemical aqueous solution after being heated to the specific temperature, so that the surfaces of the parts are blue; g, shot blasting is performed as follows: steel shots in the required diameter areblasted to the surfaces of the parts as required, uniform small pits are formed, and thus the surface fatigue strength of the chains is enhanced; h, surface treatment is performed as follows: the chains are placed in impregnating equipment and are immersed in paint, and the surfaces of the chains are coated with the paint; and i, drying is performed as follows: the chains are conveyed into a drying chamber to dry the paint on the chains, and chain finished products are obtained.

Description

technical field [0001] The invention belongs to the technical field of chain production, and in particular relates to a chain processing technology. Background technique [0002] Chains are generally metal links or rings, which are mostly used for mechanical transmission and traction. Chains used to obstruct traffic passages (such as in streets, rivers or harbor entrances), chains for mechanical transmission. [0003] The tow chain is a kind of chain that is dragged by a trailer to damage the vehicle after a driving failure. The general tow chain needs to be surface treated before leaving the factory to prevent the chain from being oxidized; the existing surface treatment is generally dipped in paint. After soaking in the paint for a certain period of time, take it out. The chain is in a static state in the paint. It is inevitable that there will be dead corners that cannot be dipped in the paint. After the chain is put into the paint, it is inconvenient to directly remove ...

[0003] The tow chain is a kind of chain that is dragged by a trailer to damage the vehicle after a driving failure. The general tow chain needs to be surface treated before leaving the factory to prevent the chain from being oxidized; the existing surface treatment is generally dipped in paint. After soaking in the paint for a certain period of time, take it out. The chain is still in the paint. It is inevitable that there will be dead corners that cannot be dipped in the paint. It is easy to carry a lot of paint when collecting the chain, resulting in a lot of waste of paint
